Need asssistance changing App View Size in MFC SDI App!

[pghTech]

I have created a SDI using VC++ 2005 w/ MFC, and I was hoping someone could tell me how to make the following view changes:

1) When you run the application, I would like for it to default to full screen, BUT I would like for it to just make the application full screen at a default limited width. For example, when you create a Dialog based MFC app, and you maximize the application it just makes the window no bigger than the actual size of the form.

- Currently now, it opens not maximized, there for showing only 1/2 the dialog window, with a horizontal scroll bar. Once you maximize the window, it takes up the complete screen with the application only taking up the left half, and a bunch of dead space on the right ~ half the screen. I would Like it to maximize to only the actual dialog window size.

Any suggestions

Well, this is the non-MFC way to do it, but there's probably an equivalent:

While processing the WM_SIZE message, change the x extents to 0 and the width of the screen, which can be gotten from SystemMetrics. This will force the window to always be the width of the screen. If I remember correctly, WM_SIZE gets sent before the window is first made visible.

Is there an "OnSize" method in MFC?
